OBJECTIVE
The aim of this study was to identify factors most relevant to postoperative nausea and vomiting (PONV) and determine the association of Helicobacter pylori with PONV.
METHODS
A cross-sectional analytic survey was conducted on 127 elective patients who underwent general and urological surgery at Sina Hospital in Tehran between March 2005 and March 2006. Related factors considered to have a possible effect on the prevalence of PONV events were evaluated by using a special questionnaire and serological laboratory test of H. pylori. Data was analyzed using t test and chi2 test and logistic regression analysis for comparing the variables.
RESULTS
Prevalence of PONV was 54.7% in patients having H. pylori infection. There was no relationship between H. pylori infection and PONV (p>0.05). Prior history of PONV was a significant risk factor for increasing the prevalence of PONV (p<0.05). Also, history of PONV beside female gender, overweighting/obesity and operation type (urologic surgery) could increase the severity of PONV (p<0.05). But, administration of opioids could decrease the severity of PONV (p<0.05).
CONCLUSIONS
It was found that PONV had a high prevalence among patients undergoing urologic and general surgery. H. pylori infection cannot affect the prevalence of PONV. More surveys are needed to develop effective protocols for preventing this common and unpleasant problem.
